Operate the machine and check whether the hazardous movement
stops under the hereafter mentioned circumstances.
1 Hazardous machine parts do not move when the protection field is
interrupted
2 The hazardous machine movement is immediately stopped, when
the protection field is interrupted with the test rod directly at the
emitter, directly at the receiver and in the middle between the emitter
and the receiver
3 No hazardous machine movement when the test rod is within the
protection field
4 The hazardous machine movement comes to standstill, when the
voltage supply of the AOPD is switched off
6.4 Half-yearly inspection
The following items must be checked every six months or when a
machine setting is changed
1 Machine stops or does not inhibit any safety function
2 No machine modification or connection change, which affects the
safety system, has taken place
3 The outputs of the AOPD are correctly connected to the machine
4 The total response time of the machine does not exceed the
response time calculated during the first commissioning
5 The cables, the connectors, the caps and the mounting angles are in
perfect condition
6.5 Cleaning
If the optics cover of the sensors is extremely soiled, the OSSD outputs
may be disabled Clean with a clean, soft cloth with low pressure
The use of agressive, abrasive or scratching cleaning agents, which
could attack the surface, is prohibited
